Sacoila Raf., Fl. Tellur. 2: 86, 1837. 
Etymology: Saccos = bag and koilos = hollow, describing 
the spur-like extension formed by the bases of 
the lateral sepals. 
Sepals free, subsimilar connivent; dorsal sepal concave; lateral 
sepals decurrent on column-foot, and together form a more or 
less free-projecting, spur-like extension. Petals agglutinate with 
dorsal sepal, basally decurrent on column-foot. Lip sessile, from 
a cuneate base conduplicate, somewhat arcuate, margins in 
middle agglutinate with sides of column, at base with linear 
thickenings. Column short, stout, basally extended in a long 
foot which is decurrent on sides of ovary with the end protrud- 
ing into a free tip; stigmata terminal, 2, confluent; rostellum 
rigid, linear-acicular, sharp-pointed. Anther ovate, acute or 
acuminate, concave, much shorter than the rostellum; pollinia 
narrowly clavate with a linear viscidium. Ovary clavate to fusi- 
form, with a short pedicel, somewhat twisted. 
Terrestrial plants. Roots fasciculate, tuberous. Leaves com- 
monly hysteranthus, when synanthus either basal or cauline, 
cuneate, sessile. Stem erect, vaginate or bracteolate, terminated 
by subdense, many-flowered raceme. Flowers large, often showy.
